BLEServer

Overview

This project demonstrates communication between two ESP32 devices using Bluetooth Low Energy (BLE) with the BLEServer library. The setup involves a server-client architecture where data is exchanged seamlessly between the two devices.

Important

To ensure both codes work seamlessly together, please refer to the BLEClient repository. It is crucial to make both the server and client codes work in tandem for successful communication and data exchange.

Features

  • UUID Characteristics: Utilizes UUID characteristics for sending and receiving data.
  • Potentiometer Data Processing: The server reads and processes potentiometer data.
  • PWM LED Control: The client uses the received data to control an LED with Pulse Width Modulation (PWM).

Detailed Description

Server Side

  • Reads potentiometer data.
  • Processes the data.
  • Sends the processed data to the client via BLE.

Client Side

  • Receives data from the server.
  • Uses the data to control an LED with PWM.
